Abstract:

An apparatus for non-permanent conversion of a semiautomatic pistol into
a compressed gas powered weapon simulator. The apparatus replaces the
pistol's barrel, recoil spring and magazine with no modification of the
pistol, which allows retaining the operational functions of the pistol's
remaining components. Compressed gas, from the simulation magazine unit,
is used in the compressed gas valve means, in the barrel unit, to operate
the slide mechanism, to compress the simulation recoil spring, and to
emit a laser pulse beam on a target when activated by the firing
mechanism; and battery power, from the simulation magazine unit, is used
to count the number of shots, lock the slide after a predetermined number
of shots and transmit information from the weapon simulator to a remote
data system. The compressed simulation recoil spring returns the slide
mechanism back to its original position, unless locked open by the
apparatus.

Description:

BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] The present invention relates to a novel apparatus for converting a
semiautomatic pistol (hereinafter referred to as a "pistol") into a
simulator so that the pistol converted into a simulator (hereinafter
referred to as a "weapon simulator") can be used for training individuals
in the use of a semiautomatic pistol without having to fire live
ammunition. More particularly, the weapon simulator provides a realistic
firing sensation by providing the proper feel and balance, the proper
trigger response, the proper action of the slide mechanism, the proper
recoil and the locking of the slide mechanism in the proper position
after the specific number of shots have been fired by the weapon
simulator, while marking the point of aim with a laser, which makes the
weapon simulator a safe, realistic and cost effective training tool.

[0003] 2. Prior Art

[0004] Various attempts have been made to develop a realistic weapon
simulator or to retrofit a working pistol into a simulator with limited
success. From U.S. Pat. No. 4,380,437, a laser beam weapon is known that
is connected to a source of compressed air via a hose-pipe to push back
the carriage. The disclosed weapon is a special replica with a modified
trigger mechanism. The combination of the features of this weapon
prevents it from providing a realistic feel of a real weapon. The firearm
recoil simulator disclosed in U.S. Pat. No. 4,480,999 provides a recoil
system via an air line coming in through the nuzzle, which does not leave
room for a laser pointer in the barrel and the simulator has a bulky air
valve that hangs from the handle of the simulator that prevents the
simulator from duplicating the feel of a real weapon. The retrofittable
laser and recoil system for a firearm described in U.S. Pat. No.
5,842,300 does retrofit an actual firearm, however, the recoiling element
is placed in the magazine. The recoiling element does not push back the
slide and does not cycle the semiautomatic weapon's mechanism, thus only
offering limited realism. The simulated weapon described in U.S. Pat. No.
5,947,738 uses a special gas cartridge in the barrel of the weapon to
activate a pressure switch within the barrel to activate a light emitter
and does not provide a realistic feel of a real weapon. The laser pistol
described in U.S. Pat. No. 6,146,141 is a replica of a weapon that has an
electronic trigger mechanism that does not offer the realistic feel of a
real weapon. The laser pistol described in U.S. Pat. No. 6,682,350 has
several shortcomings as a simulator. The simulator uses a magazine
connection piece, which takes up space in the magazine well, therefore a
reduced size magazine must be used to maintain the original gun's shape.
This reduced size magazine does not leave room for a slide catch
mechanism. The simulator uses a hose coupling between the magazine
connection piece and the compressed gas cylinder that is difficult to
connect and keep connected. The simulator has a connection valve with a
protruding pin on top of the magazine, which can hang up when received
into the simulator. The simulator has a separate fill valve at the bottom
of the magazine that is used to either fill the magazine or attach a hose
to provide compressed gas to the simulator. The simulator also uses a
switchover valve to activate the valve tappet that complicates the firing
mechanism and the compressed gas vents through a slip fit around the
striker that reduces the efficiency of the simulator. The above-discussed
attributes of the simulator provide for a very complicated and
inefficient retrofit to a real weapon. The training firearm discussed in
U.S. Pat. No. 6,869,285 can be a retrofitted pistol with a blow-back
assembly that uses a CO2 cartridge in a modified magazine. The recoil
actuator of this simulator is built into the rear portion of the original
pistol slide; therefore it requires the weapon slide to be milled out and
is then no longer usable for live ammunition. Also, a flexible hose
connection between the magazine and barrel is problematic. In this
simulator, the magazine cannot be removed easily due to the magazine
being tethered to the blow-hack assembly in the barrel of the gun and the
design of the magazine does not provide room for a slide catch. These
changes prevent the simulator from providing a realistic feel of a real
weapon. The bolt locking assembly for firearm simulators described in
U.S. Pat. No. 7,197,973 provides slide lock simulation by
electro-pneumatic means using a pneumatic recoil valve with a pilot
valve, which can only be applied to a specially built simulated firearm.
This prevents the simulator from being able to provide the realistic feel
of a real weapon. The simulator described in U.S. Pat. No. 7,306,462 has
a low-pressure gas recoiling system controlled by an electric pilot
valve. This is a more complex design that requires both electricity and
gas to produce recoil in the simulator.

[0005] The disadvantage of known simulators is that they are either built
as non/firing gas operated replicas or they are converted real pistols
where the conversion of the pistol to a simulator is difficult to
implement, the conversion often requiring a specially trained technician
to install the conversion components into the pistol and often making the
conversion of the pistol to a simulator irreversible.

[0006] Therefore, there is a need in the art for an apparatus for
converting a pistol into a weapon simulator so that the weapon simulator
provides a realistic firing sensation by providing the proper feel and
balance, the proper trigger response, the proper action of the slide
mechanism, and the proper recoil without the drawbacks of the present
prior art.

[0007] It is therefore desirable to develop a novel apparatus for
converting a pistol into a weapon simulator that does not require
permanent alternation to the pistol to allow the pistol to accommodate
the apparatus so that the pistol can alternate between being a weapon
simulator and being a working pistol that fires live ammunition.

[0008] It is also desirable to develop a novel apparatus for converting a
pistol into a weapon simulator such that the apparatus does not require
special tools to convert the pistol into a weapon simulator.

[0009] It is also desirable to develop a new apparatus that converts a
real pistol, that fires live ammunition, to a weapon simulator, that
fires a laser pulse beam, so that training to use the pistol can be
accomplished in a safe environment.

[0010] It is also desirable to develop a new apparatus for converting a
pistol to a weapon simulator that uses a standard source of compressed
gas that can easily obtained in the marketplace and can be easily
replaced in the simulator when the compressed gas has been expended.

[0011] It is also desirable to develop a new apparatus for converting a
pistol to a weapon simulator that uses only a pneumatic source of energy
to operate the weapon simulator.

[0012] It is also desirable to develop a new apparatus for converting a
pistol that allows the use of a means for providing a remote source of
compressed gas that does not require a permanent modification to the
pistol.

[0013] It is also desirable to develop a new apparatus for converting a
pistol that count shots and locks the slide of the weapon in the open
position after the correct number of shots are fired by the weapon
simulator to replicate a pistol's response to the last bullet being fired
by the pistol.

[0014] It is also desirable to provide a new apparatus for converting a
pistol to a weapon simulator that has a transmitter means that provides a
signal to a remote supervisory system to monitor the shots fired by the
simulator during training.

SUMMARY OF THE INVENTION

[0015] The embodiments of the present invention are directed to an
apparatus for converting a pistol into a weapon simulator (hereinafter
referred to as "apparatus") without the use of any special tools or
requiring any alterations to the pistol so that the user is given a
realistic firing sensation when they fire the weapon simulator and so
that the weapon simulator can be converted back to a pistol that is
capable of firing live ammunition. Most modern small arms are designed in
such a way that major parts can be easily removed for cleaning and
maintenance. Standard takedown procedures for cleaning and maintenance of
a pistol are provided to the user by the pistol manufacturer and are also
part of standard drill in armed forces. The removal and reinstallation of
the barrel and recoil spring in a pistol or replacement of an empty
magazine with a full magazine are skills entirely within the capabilities
of an average shooter and are typically required for qualification in
organized weapon training. The installation of the apparatus for
converting a pistol into a weapon simulator has been simplified so that
the installation of this novel apparatus to convert a pistol into a
weapon simulator does not require more than these basic skills.

[0016] Embodiments of the invention may include one or more of the
following features. The apparatus includes a barrel unit, a simulation
recoil spring and a simulation magazine unit that replaces the original
components in the pistol to convert the pistol to a weapon simulator. The
weapon simulator utilizes the frame, the locking block, the slide
mechanism, the disassembly latch, the magazine catch and the firing
mechanism that are the original components of the pistol where the slide
mechanism has a slide and a slide latch. The slide having a rest position
and an open position such that the rest position is where the slide is
found on the weapon frame before firing the weapon simulator or the
pistol and such that the open position is where the slide is found on the
weapon frame after the weapon simulator or pistol is fired or where the
slide is locked on the weapon frame after all ammunition has been fired
from the magazine of the pistol. The simulation magazine unit contains a
compressed gas source to provide the energy to operate the weapon
simulator. The barrel unit is connected to the simulation magazine unit
so that the compressed gas flows from the compressed gas source to the
barrel unit. The barrel unit contains a compressed gas valve means that
interacts with the firing mechanism so that compressed gas is released in
the compressed gas valve means such that the compressed gas valve means
forces the slide to move from its rest position to its open position,
thereby compressing the simulation recoil spring. Once the compressed gas
flows through the compressed gas valve means and is vented to the outside
of the weapon frame, the energy from the compressed simulation recoil
spring causes the slide to move from its open position to its rest
position, which moves the compressed gas valve means so that the
compressed gas valve means seals off the compressed gas flow path. The
barrel unit may include a laser beam pulse means that is actuated by a
laser beam actuation means that is responsive to when the weapon
simulator is fired whereby the laser beam actuation means signals the
laser beam pulse means to emit a laser beam onto a target. The barrel
unit may consist of two or more components to allow the conversion of a
pistol that has a weapon frame that will not accommodate a one-piece
barrel unit. The compressed gas valve means may contain a step piston to
provide for a gradual recoil instead of an abrupt recoil, as an abrupt
recoil causes violent muzzle movement in the vertical direction and
therefore the laser beam creates a streak on the target instead of a
point. The simulation magazine unit may also contain a slide catch means
that counts shots fired by the weapon simulator and locks the slide in
the open position after the appropriate number of shots are fired by the
weapon simulator to replicate a pistol's response to the last bullet
being fired by the pistol where the slide is locked in the open position
when the magazine is empty of live ammunition. The simulation magazine
unit may also contain a transmitter means that provides a wireless
connection for sending data from the weapon simulator and a remote
supervisory system to provide information from the weapon simulator such
as the number of shots fired by the weapon simulator during training. The
present invention is directed to an apparatus to convert a pistol to a
weapon simulator that replaces only the original barrel, recoil spring
and magazine in the pistol with a uniquely designed barrel unit,
simulation recoil spring and simulation magazine unit that drops neatly
in place in the weapon frame and does not interfere with any of the other
components of the unmodified pistol. In fact, the present invention takes
advantage of the remaining major components of the original pistol with
the philosophy that since the pistol already has these other components,
why not make use of them in the weapon simulator. In particular, the
present invention utilizes an unaltered trigger, where the trigger is
part of the firing mechanism, in the weapon simulator. This means that
the shooter's feel of pressing the trigger is exactly the same in the
weapon simulator as it is in the pistol when firing live ammunition. This
attribute of the weapon simulator is very important for proper training
and for the shooter to become use to their own pistol for the simple
reason that trigger characteristics greatly affect the practical accuracy
of shooting the pistol. In the present invention, the weapon cycle is
triggered directly by the blow or impact of the unmodified firing pin as
if it were igniting the cartridge primer of live ammunition, except in
the case of the present invention, the impact of the firing pin actuates
the compressed gas valve means. The benefit of the using the entire
original firing mechanism, without any alternations, is that all safety
elements built into the original weapon like the safety lever or safe
hammer drop lever, remain fully functional and can be practiced during
training or instruction on the use of the pistol. In comparison, most of
the simulators of prior art have had their triggers specially designed as
pneumatic or electrical switches or are surrounded with sensors that
change the trigger's characteristics from the trigger's normal
characteristics found in the pistol and they do not duplicate the
pistol's safety elements.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0043] The embodiments discussed herein are merely illustrative of
specific manners in which to make and use the invention and are not to be
interpreted as limiting the scope of the instant invention.

[0044] While the invention has been described with a certain degree of
particularity, it is to be noted that many modifications may be made in
the details of the invention's construction and the arrangement of its
components without departing from the spirit and scope of this
disclosure. It is understood that the invention is not limited to the
embodiments set forth herein for purposes of exemplification.

[0045] Referring to the figures of the drawings, wherein like numerals of
reference designate like elements throughout the several views,
particularly to FIG. 1, there is shown a schematic side elevational view
of the preferred embodiment of the present invention wherein an apparatus
for converting a pistol into a weapon simulator 9 (hereinafter referred
to as "apparatus 9") is received into a pistol to create a weapon
simulator 10. The apparatus 9 comprises a barrel unit 91, a simulation
recoil spring 55 and a simulation magazine unit 60. The installation of
the apparatus 9 into the pistol, utilizing the firearm manufacturer's
normal disassembly and assembly procedures without the need for any
special tools or modification of any part of the original pistol, allows
converting a pistol to a compressed gas powered weapon simulator 10 and
then allows the weapon simulator 10 to be converted back into a pistol by
removing the apparatus 9 and reinstalling the original barrel, recoil
spring and magazine utilizing the same disassembly and assembly
procedures. The weapon simulator 10 uses a compressed gas source means
163 to provide a compressed gas such that the pressure of the compressed
gas provides an energy source to actuate the weapon simulator 10 to
accomplish simulated shooting. While various methods may be used to
provide the compressed gas source means 163 used in the simulation
magazine unit 60, FIG. 1 shows the weapon simulator 10 using a standard
off-the-shelf CO2 compressed cartridge, which is ample for up to one
hundred (100) shots from the weapon simulator 10, that can be easily
replaced once pressure in the cartridge becomes so low that the weapon
simulator 10 will no longer function as the cartridge 61 in the preferred
embodiment. The CO2 cartridges are readily available and are inexpensive
to purchase which makes using the weapon simulator 10 of the present
invention convenient, safe and cost effective. Special cartridges having
pressures higher than a standard off-the-shelf CO2 cartridge could be
used as the cartridge 61 to provide more shots between replacement of the
cartridge 61. In another embodiment of the present invention as shown in
FIG. 24, a refillable high pressure gas storage means 118 is provided in
the simulation magazine unit 60 of the apparatus 9 to provide the source
of compressed gas to power the weapon simulator 10 which could use a
variety of gases as the source of compressed gas.

[0046] As shown in FIG. 1, the weapon simulator 10 utilizes the pistol's
frame 11, slide mechanism 123, magazine catch 13, disassembly latch 15
and firing mechanism 122 with no modifications to the pistol. The firing
mechanism 122 comprises a firing pin 16, a trigger 17, a trigger safety
lever 161 and a means for striking firing pin 18. The pistol's frame 11,
slide mechanism 123, magazine catch 13, disassembly latch 15 and firing
mechanism 122 perform the same functionality as part of the weapon
simulator 10 as they did as part of the pistol. In fact, the present
invention takes advantage of these remaining major components by
utilizing them in the weapon simulator 10 in order to provide a realistic
shooting experience. In particular, the present invention utilizes an
unaltered trigger 17 in the weapon simulator 10. This means, that the
shooter's feel of pressing the trigger 17 is exactly the same in the
weapon simulator 10 as it is in the pistol when firing live ammunition.
This attribute of the weapon simulator 10 is very important for proper
training and for the shooter to get used to their own pistol due to
trigger characteristics greatly affecting the accuracy of shooting the
pistol or weapon simulator 10. In the present invention, the weapon cycle
is triggered directly by the blow or impact of the unmodified firing pin
16 as if it were igniting the cartridge primer of live ammunition. The
benefit of using the entire original firing mechanism 122, without any
alternations to the firing mechanism 122, means that all safety elements
built into the original weapon, like the trigger safety lever 161, remain
fully functional and can be practiced during training or instruction on
the use of the pistol. The slide mechanism 123 has a slide 12, a means
for actuating slide 162 and a slide catch 14. The slide 12 having a rest
position and an open position such that the means for actuating slide 162
moves the slide 12 between these two positions. The rest position is
where the slide 12 is found on the frame 11 before firing the pistol or
the weapon simulator 10. The open position is where the slide 12 is found
on the frame 11 after the weapon simulator 10 or pistol is fired to allow
a fired cartridge to be ejected from the pistol, to allow live ammunition
to move up from the magazine of the pistol, so that the live ammunition
is ready to be pushed into the chamber of the pistol and to cock the
firing mechanism 122 for the next shot and where the slide 12 is locked
on the frame 11 after all ammunition has been fired from the magazine of
the pistol.

[0047] In all of the embodiments of the present invention the pistol's
original barrel, recoil spring and magazine are removed and replaced with
the apparatus 9 to convert the pistol from firing live ammunition to a
weapon simulator 10. In the preferred embodiment of the present
invention, FIG. 1 shows an apparatus 9 being received in the frame 11
where the apparatus 9 comprises a barrel unit 91, a simulation recoil
spring 55 and a simulation magazine unit 60 such that the barrel unit 91,
the simulation recoil spring 55 and the simulation magazine unit 60
cooperate with the remaining components of the pistol to convert the
pistol into a weapon simulator 10. As shown in FIGS. 1, 2, 3 and 4, the
barrel unit 91 comprises a barrel 20, a compressed gas valve means 157, a
compressed gas valve retaining means 221 and a firing mechanism actuated
laser beam pulse emitting means 59. As shown in FIG. 1 and FIG. 20, the
simulation magazine unit 60 comprises a magazine frame 156, a magazine
gas sealing means 160 and a means for receiving the compressed gas from
source 222. As shown in FIG. 20, the preferred embodiment for the
compressed gas source means 163 comprises a cartridge 61 as the source
for compressed gas for the weapon simulator such that the cartridge 61 is
received into the means for receiving compressed gas source means 222
where the means for receiving compressed gas source means 222 comprises a
cartridge engagement means 64. The magazine gas sealing means 160
comprises a magazine valve assembly 119. The magazine valve assembly 119
and the cartridge engagement means 64 are received in the magazine frame
156 so that the combination of the magazine frame 156, magazine valve
assembly 119 and the cartridge engagement means 64 can be inserted and
removed from the frame 11 as a single unit as a replacement for the
original magazine. A cartridge 61 is received in the cartridge engagement
means 64 prior to the magazine frame 156 being inserted into the frame 11
whereby the cartridge 61 provides the source of compressed gas to power
the weapon simulator 10. The cartridge engagement means 64 retains and
mates the cartridge 61 with the magazine valve assembly 119 so that
compressed gas is allowed to flow into the magazine valve assembly 119
where the pressure of the compressed gas it is contained by the magazine
valve assembly 119. When the magazine frame 156 with the cartridge 61 is
received in the cartridge engagement means 64 and is inserted into the
frame 11, the magazine valve assembly 119 sealably mates with the barrel
20 of the barrel unit 91 and allows the compressed gas to flow from the
magazine valve assembly 119 into the compressed gas valve means 157. The
compressed gas valve means 157 contains the compressed gas in the barrel
20. The compressed gas valve means 157 cooperates with the firing
mechanism 122 and the slide mechanism 123 to use the pressure from the
source of compressed gas, which is the cartridge 61 in the preferred
embodiment, to operate the weapon simulator such that it replicates the
operation of the pistol, when the pistol fires live ammunition, and
provides an input to activate the firing mechanism actuated laser beam
pulse emitting means 59 to generate a laser beam pulse on a target. As
shown in FIG. 2, the compressed gas valve means 157 is received inside of
the barrel 20 and is removably retained in the barrel 20 by a compressed
gas valve retaining means 221. The compressed gas valve means 157 further
comprises a compressed gas valve assembly 125. The compressed gas valve
assembly 125, having a first valve assembly position and a second valve
assembly position, is received inside the barrel 20. The first valve
assembly position is where the compressed gas valve assembly 125 is
located in the barrel 20 before the firing mechanism 122 is engaged such
that the compressed gas valve assembly 125 has closed off the flow path
of the compressed gas. As shown in FIG. 5, the second valve assembly
position is where the compressed gas valve assembly 125 is located in the
barrel 20 after the compressed gas has moved the compressed gas valve
assembly 125 toward the rear of the weapon simulator 10 such that the
compressed gas valve assembly 125 has re-closed the flow path of the
compressed gas and the compressed gas, that has entered the compressed
gas valve assembly 125, has been vented from the interior of the
compressed gas valve assembly 125. When the slide 12 of the slide
mechanism 123 is in its rest position and the compressed gas valve
assembly 125 is in its first position, the compressed gas valve assembly
125 contains the compressed gas in the barrel 20 by closing off the flow
path for the compressed gas. When the shooter engages the firing
mechanism 122 by pulling the trigger 17, the means for striking the
firing pin 18 strikes the firing pin 16 which moves the firing pin 16
along the predetermined path so that the firing pin 16 comes in contact
with the compressed gas valve assembly 125 with enough force to open the
flow path for the compressed gas in the compressed gas valve assembly
125. When the flow path is opened in the compressed gas valve assembly
125, the compressed gas moves the compressed gas valve assembly 125
toward the rear of the weapon simulator 10 to its second position such
that the compressed gas valve assembly 125 and means for actuating slide
162 cooperate to move the slide 12 from its rest position to its open
position and to compress the simulation recoil spring 55. Once the
compressed gas valve assembly 125 reaches its second position, the
compressed gas valve assembly 125 has closed the flow path of the
compressed gas and the compressed gas that has entered into the
compressed gas valve assembly 125 is vented from the interior of the
compressed gas valve assembly 125. Once venting has occurred, the
compressed simulation recoil spring 55 cooperates with the means for
actuating slide 162 to return the slide 12 to its rest position and the
compressed gas valve assembly 125 to its first position. A more complete
understanding of the new and novel features of the preferred embodiment
of the present invention will be better understood from a more detailed
description of the apparatus 9 shown in FIGS. 1 through 5, FIG. 13 and

[0125] As shown in FIG. 24, this embodiment of the simulation magazine
unit 60 having a shot counting means 196 that counts the number of shots
fired by the weapon simulator 10 to provide a predetermined output when a
predefined number of shots are counted by the shot counting means 196.
Once the predefined numbers of shots have been counted by the shot
counting means 196, the shot counting means 196 provides an input to the
slide catch means 197 to cause the slide catch means 197 to interact with
the slide latch 14 to catch the slide 12 in the open position. The remote
communication means 198 contained in the simulation magazine unit 60
provides an interface with a remote supervisory system to transmit
information from the weapon simulator 10 such as when the weapon
simulator fires a shot and when the weapon simulator 10 has fired a
predetermined number of shots and the slide is latched in the open
position. The shot counting means 196, the slide catch means 197 and the
remote communication means 198 are powered by the magazine power means
199 where the magazine power means 199 is rechargeable by an external
charger. As shown in FIG. 24, one embodiment of the shot counting means
196 comprises a microprocessor 76, a magazine proximity switch 77, and a
vibration sensor 79. The microprocessor 76 and the vibration sensor 79
are mounted to a circuit board 75 where the circuit board 75 is received
in the magazine frame 156 in a predetermined location. The magazine
proximity switch 77 situated in a predetermined location in the magazine
frame 156 so that the magazine proximity switch 77 is actuated when the
simulation magazine unit 60 is inserted into the frame 11 such that when
the simulation magazine unit 60 is received in the frame 11 the magazine
proximity switch 77 allows electricity from the magazine power means 199
to flow to the microprocessor 76 to activate the microprocessor 76. The
vibration of the slide mechanism 123 moving the slide 12 from its rest
position to the open position activates the vibration sensor 79 so that
the vibration sensor 79 provides an input to the microprocessor 76
whereby the microprocessor 76 counts the input from the vibration sensor
79 as a shot fired by the weapon simulator 10. In an alternative
embodiment, the vibration sensor 79 is replaced by a slide proximity
switch 78 where the slide proximity switch 78 is situated in the magazine
frame 156 such that the sensor part of the slide proximity switch 78
extends beyond the magazine frame top 206 to allow the slide proximity
switch 78 to interact with the slide 12 such that the slide proximity
switch 78 provides an input to the microprocessor 76 each time the slide
12 moves from its rest position to its open position then back to its
rest position whereby the microprocessor 76 counts the input from the
slide proximity switch 78 as a shot fired by the weapon simulator 10.

[0126] In the embodiment shown in FIG. 24, the slide catch means 197
comprises a gear motor 85, a transmission 86, a drive nut 87, a slide
catch riser spring 89 and a slide catch riser 90. Once the microprocessor
76 has counted the predetermined number of shots, based upon the input of
either the vibration sensor 79 or the slide proximity switch 78, then the
microprocessor 76 activates the gear motor 85 where the gear motor 85
drives the transmission 86. The transmission 86 causes the drive nut 87;
where the drive nut 87 having a predetermined outside dimension is
received on the plurality of high pressure gas housing body threads 203;
to rotate on the plurality of high gas housing body threads 203 to move
the drive nut 87 toward the top of the magazine frame 156. The slide
catch riser spring 89 is situated between the drive nut 87 and the slide
catch riser 90. The slide catch riser spring 89 being made from metal or
metal alloy material having a predetermined shape that is substantially a
spiral shape with a predetermined inside diameter that is more than the
plurality of high pressure gas housing body threads and having a
predetermined outside diameter of the slide catch riser spring 89 that is
less than the predetermined outside dimension of the drive nut 87 such
that as the drive nut 87 is driven toward the top of the magazine frame
156 by the transmission 86 the drive nut 87 compresses the slide catch
riser spring 89 against the slide catch riser 90. As the drive nut 87
cooperates with the slide catch riser spring 89 to put pressure on the
slide catch riser 90 such that the slide catch riser 90 is pushed through
the magazine frame top 206 so that the slide catch riser 90 interacts
with the slide catch 14. When the slide mechanism 123 causes the slide 12
to move from its rest position to its open position, the slide catch
riser 90 causes the slide catch 14 to catch the slide 12 in its open
position in response to the predefined number of shots has been fired by
the weapon simulator 10. By actuating the gear motor 85 in the opposite
direction, the transmission moves the drive nut 87 away from the top of
the magazine frame 156 which releases the tension from the slide catch
riser spring 89 on the slide catch riser 90 such that the slide catch 14
can push the slide catch riser 90 back down into the magazine frame 156
and release the slide 12 to allow the slide 12 to return to its rest
position.

[0127] The remote communication means 198 is received in the magazine
frame 156 to provide an interface with a remote supervisory system to
transmit information from the weapon simulator 10 such as when the weapon
simulator fires a shot and when the weapon simulator 10 has fired a
predetermined number of shots and the slide is latched in the open
position to a remote supervisory control and data acquisition (SCADA)
system. As shown in FIG. 24, remote communication means 198 in this
embodiment comprises a radio transmitter module 81 and an antenna 82.
Other configurations of the remote communication means 198 may be
utilized to transmit information from the weapon simulator to the remote
SCADA system. The radio transmitter module 81 receives inputs from the
microprocessor 76 where the radio transmitter 81 converts the inputs from
the microprocessor 76 into radio signals and transmits these radio
signals over the antenna 82. The radio transmitter module 81 is
electrically and physically connected to the circuit board 75 in a
predetermined position so that the radio transmitter 81 receives an
electrical input from the microprocessor 76 and electricity from the
magazine power means 199 is allowed to flow to the radio transmitter
module 81 to power the radio transmitter module 81.

[0128] The magazine power means 199 is received in the magazine frame 156
to provide electricity to the electrical components received in the
simulation magazine unit 60. As shown in FIG. 24, the magazine power
means 199 provides electrical power to the magazine proximity switch 77,
the microprocessor 76, either the vibration sensor 79 or the slide
proximity switch 78, the radio transmitter module 81 and the gear motor
85 and comprises a magazine battery 83, a power module 208, a light
emitting diode 80 and a magazine battery charging plug 84. A remote
battery charger that plugs in to a standard 120-volt receptacle has a
male plug that is received in the magazine battery charging plug 84 to
charge the magazine battery 83. The magazine battery charging plug 84 is
received in a predetermined location the magazine frame bottom 207 such
that the magazine battery charging plug 84 can receive the male plug from
the remote battery charger. The magazine battery charging plug 84 is
electrically connected to the magazine battery 83 such that it allows
electrical current to flow from the remote charger through the magazine
battery charging plug 84 into the magazine battery 83 to charge the
magazine battery 83. The magazine battery 83 is received in the magazine
frame 156 in a predetermined location and is electrically connected to
the power module 208. The power module 208 is physically and electrically
connected in a predetermined location on the circuit board 75 so that the
power module 84 receives a predetermined level of electricity from the
magazine battery 83 and allows predetermined level of electricity to flow
to each electrical powered component in the simulation magazine unit 60.
The light emitting diode 80 is electrically connected to the power module
208 to receive a predetermined level of electricity from the power module
208 so that the light emitting diode 80 provides a visual indication that
the magazine battery 83 is providing an acceptable level of voltage
whereby the shooter knows when the magazine battery 83 is not providing
an acceptable level of voltage and needs to be connected to the remote
battery charger to charge the magazine battery 83. The light emitting
diode 80 is located in a predetermined location on the circuit board 75
so that it can be electrically connected to the power module 208 and in a
predetermined location in the magazine frame 156 so that the light
emitting diode 80 can be seen when the simulation magazine unit 60 is
received in the frame 11.

[0129] A fifth embodiment of the magazine unit 60 is shown in FIG. 25.
This embodiment has the same features as the embodiment shown in FIG. 24,
except the slide catch means 197 comprises a latching solenoid 215, a
plurality of slide catch riser springs 89 and a slide catch riser 90. The
latching solenoid 215 having a latching solenoid plunger 216, a latching
solenoid coil 217 and at least one latching solenoid magnet 218. The
latching solenoid plunger 216 has two stable positions, a captured
position and a released position. The latching solenoid plunger 216 will
remain in either of these positions without consuming any electrical
power. The latching solenoid plunger 216 slidably moves between the
captured position and the released position inside the latching solenoid
coil 217. The captured position is where the latching solenoid plunger
216 is fully received inside the de-energized latching solenoid coil 217
and held in this location by the latching solenoid magnet 218. The
released position is where the latching plunger 216 is fully extended
outside of the latching solenoid coil 217. The latching solenoid plunger
216 is moved from the captured position to the released position when a
short impulse of power is applied to the latching solenoid coil 217 that
both neutralizes the plurality of latching solenoid magnets 218 and
develops a magnetic force to allow the latching solenoid plunger 216 to
be moved from being fully received inside the latching solenoid coil 217
to being fully extended outside the latching solenoid coil 217. The
latching solenoid plunger 216 is moved from the released position to the
captured position by manually pushing the latching solenoid plunger 216
from being fully extended outside the latching solenoid coil 217 to being
fully received inside the latching solenoid coil 217 to allow the
latching solenoid magnet 218 to hold the latching solenoid plunger 216 in
the captured position. The end of the latching solenoid plunger 216 that
extends outside of the latching solenoid coil 217 is coupled to the slide
catch riser 90 such that the plurality of slide catch riser springs 89
are situated in a predetermined position between the latching solenoid
215 and the slide catch riser 90 and situated in a predetermined position
between the high pressure gas housing 120 and the slide catch riser 90
where the catch riser springs 89 are compressed when the latching
solenoid plunger 216 is in the captured position so as to place a
predetermined amount of force on the combination of the slide catch riser
90 and the latching solenoid plunger 216 that is less than the force
placed upon the latching solenoid plunger 216 by the latching solenoid
magnet 218 so that the latching solenoid magnet 218 hold the latching
solenoid plunger in the captured position and where the catch riser
springs 89 aid the latching solenoid coil 217 to move the combination of
the slide catch riser 90 and the latching solenoid plunger 216 to the
released position when a pulse of electrical power is applied to the
latching solenoid coil 217. In alternative embodiments, a single catch
riser spring 89 can be situated between the slide catch riser 90 and the
high pressure gas housing 120 or be situated between the slide catch
riser 90 and the latching solenoid 215.

[0130] Once the microprocessor 76 has counted the predetermined number of
shots, based upon the input of either the vibration sensor 79 or the
slide proximity switch 78, then the microprocessor 76 provides a pulse of
electrical power to the latching solenoid coil 217 that neutralizes the
latching solenoid magnet 218 and develops a magnetic force, aided by the
catch riser spring 89, to move the latching solenoid plunger 216 from its
captured position to its released position. As the latching solenoid coil
217 cooperates with the slide catch riser spring 89 to put pressure on
the combination of the latching solenoid plunger 216 and the slide catch
riser 90 such that the slide catch riser 90 is pushed through the
magazine frame top 206 so that the slide catch riser 90 interacts with
the slide catch 14. When the slide mechanism 123 causes the slide 12 to
move from its rest position to its open position, the slide catch riser
90 causes the slide catch 14 to catch the slide 12 in its open position
in response to the predefined number of shots having been fired by the
weapon simulator 10, just like a pistol would normally do when the last
round is fired from it. Once the slide 12 has been held in its open
position, the shooter has to remove the simulation magazine unit 60 and
manually depress the slide catch riser 90 back down into the simulation
magazine unit 60, which pushes the latching solenoid plunger 216 back to
its captured position where the latching solenoid magnet 218 hold the
combination of the latching solenoid plunger 216 and the slide catch
riser 90 in place inside the simulation magazine unit 60 and compresses
the catch riser spring 89. The shooter can then reinsert the simulation
magazine unit 60 back into the weapon simulator 10 in order to release
the slide 12 to allow the slide 12 to return to its rest position. This
simulates real life shooting where the shooter would remove the emptied
magazine and manually load rounds of ammunition into the magazine and
reinsert the refilled magazine into the pistol. This embodiment extends
the time before the magazine power means requires recharging due to using
less power to activate the slide catch riser 90. In alternative
embodiments, the placement of the latching solenoid 215 within the
simulation magazine unit 60 can be in other predetermined locations than
shown in FIG. 25. In order to accommodate the other predetermined
locations of the latching solenoid 215 within the simulation magazine
unit 60, the slide catch riser 90 has an alternate predetermined shape
that allows the slide catch riser 90 to be coupled to the latch solenoid
plunger 216 of the latching solenoid 215.

[0131] Whereas, the present invention has been described in relation to
the drawings attached hereto, it should be understood that other and
further modifications, apart from those shown or suggested herein, may be
made within the spirit and scope of this invention.
